Design of a Quasi-Zero Stiffness Vibration Isolator Based on Cosine Curved Beams

To improve low-frequency vibration isolation while maintaining load-bearing stability, this paper proposes a quasi-zero-stiffness (QZS) vibration isolator based on cosine-curved flexible beams. The isolator consists of a rigid frame and two mutually perpendicular curved beams, whose geometric nonlinearity is used to re...
